For the cyclic process data exchange and the acyclic parameter access, separate
function blocks are used.
Note
In OB1, the FC10 “Simulation” is called up. Here, FC10 simulates a user
program, by creating a control word and setpoint using the digital inputs.
Since it is only used here to make the example program runnable, it is not further
discussed.
